Hi, i would really like your judgement on whether or not the spots on
the hull of this boat, reveals a case of osmosis?

I just bought this one, a Hurley 22 from 1971, despite a lack of
thorough knowledge on boats. I have talked to several knowledgeable and
helpful people, who states it to be in fairly good condition. From the
outside it certainly does not show any hints of osmosis, but then i
look at this picture and get nervous. I havent heard of cases in which
it could be identified from the inside despite looking healthy on the
outside, but i cant help thinking that the spots on the very left of
this photo kind of looks like osmosis.

What do you think?

Best regards, Martin

This looks like it's dirty & in need of TLC, but not osmotic since
osmosis most often crops up under the relatively impermeable gelcoat
layer. My own boat (an old Ensenada 20) has several spots where it
looks like hey just fiberglassed some wooden blocks inside the hull
with cable wrapped around them during the boat build (presumably to
lift it from the mold) then just cut the cables flush and left it
all, so some of these things may be artifacts of the boat's original
construction.
